Description

Rosette and lower pitchers are cylindrical throughout and have a small horizontal mouth. Unusually, they lack ventral wings. The lid is broadly triangular and lacks appendages. Pitchers are yellowish with dark speckles and a striped peristome.

Upper pitchers are generally infundibular, although their shape may vary from narrowly funnel-shaped to distinctly bulbous in the upper portion. This bulbous portion corresponds to the upper waxy zone of the inner surface.
